Modeling viscosity. Shear strain=Shear rate?

Hello,
I'm developing a UDF for introducing the Cross-WLF viscosity model. In the Cross-WLF model there's the shear rate variable (see the image). In the UDF I am using the following code for defining the shear rate: real shear_rate=C_STRAIN_RATE_MAG(cell,thread); My doubt is: Is the strain rate the same as the shear rate? In case of no, how should I obtain the shear_rate value from ANSYS in the UDF? |

Please, does somebody know if shear strain is the same of shear rate?
And, if not, how do I obtain "shear rate" in a UDF? |

Hi jpina, were you able to formulate the UDF then?
